Orange prawn flies like the GP, The Chilimps and Ally’s Scrimp, to mention a few – Have a substantial effect on sea trout and salmon living in peaty water – Why? White light (daylight) is divided into all the colours of the rainbow – and the different colours that the light is made up of will disappear through water – in peaty water, the last colour to fade is; red.

This variant of the General Practitioner is yet another fly designed for a special presentation. It has caught me much fish over the years and has a particular goal; it is the fly I bring out when the fish is hanging close to the edge of the other river bank of a medium river. A cast straight across could be the only way to cover the specific lie – The General Practitioner will only have a few seconds to find the depth of the fish before the fly line starts pulling away. This is the time for the Heavy Metal General Practitioner. If tied correctly, this fly looks like a crustacean.

Thin 1, 4-millimetre tubing melted in one end to form a collar. Hook guard in place (here red tubing – clear tubing will also do) – Note the yellow line sticking out of the tube to the right: It is nylon mono 0.40 millimetre. I use it to put through the eye of the needle to wedge the tubing onto the needle, preventing it from revolving.

Buy tubing and the needle from the E-shop

Cut the centre out of a hot orange Golden Pheasant tippet feather to form a V-shaped feather. Place this on top of the fly, as seen in the photo. Fly seen from above. Tie in a length of silver rib. The tippet feather-like many other feathers, is a highly efficient salmon attractor worth implementing in all kinds of sub-flies

Tie in a body of wool. Here I have used hot orange seal fur. Regular wool will also do. Run the ribbing through the body, and plug the hairs out – No hackle is needed in the construction

Seen from the side, the General Practitioner should look something like this

Tie down the hook guard – Apply super-glue or fly-tying cement to tie down the tube where the metal section will sit – Slide down the copper bullet. Bullets like this can be bought in various sizes and colours.

Cut a bunch of hot orange hairs out. Here hair from a polar bear. Separate small from long hair, and start by tying in the bundle of short hair. Put the longer hair on top of this bundle. Tying the General Practitioner in this way will prevent the hair from getting caught in the bend of the hook/hooks

Tie in a uniform Golden Pheasant breast feather, flat on the top of the fly. Here seen from above. The feather has to be tied in perfectly – straight on top. This is the difficult part of this type of fly. If you don’t get it right, the fly won’t work probably
